Grand Junction is the 15th most populous city in the State of Colorado and the most populous city on the Colorado Western Slope. Grand Junction serves as a major commercial and transportation hub within the large area between the Green River and the Continental Divide. It is the principal city of the Grand Junction Metropolitan Statistical Area which had a population of 139,137 in 2007. The city is located along the Colorado River, where it receives the Gunnison River from the south. The name "Grand" refers to the historical upper Colorado River until renamed in 1921, and the word "Junction" is from the joining of the Colorado and Gunnison rivers. Hence, Grand Junction has been given the nickname "River City". The city sits near the mid-point of a 30-mile (48 km) arcing valley, known as the Grand Valley, a major fruit-growing region, historically home to the Ute people and settled by white farmers in the 1880s. In recent years, several wineries have been established in the area as well. The Colorado National Monument, a unique series of canyons and mesas, overlooks the city on the west, while most of the area is surrounded by public lands managed by the Bureau of Land Management. The Book Cliffs are a prominent series of cliffs that define the northern side of the Grand Valley. Interstate 70 connects the city eastward to Glenwood Springs and Denver and westward to Green River, UT and Interstate 15. Grand Junction was the boyhood home (1124 Gunnison Avenue) of Dalton Trumbo (1905-1976), Academy Award-winning screenwriter (Exodus, Spartacus, Roman Holiday, Thirty Seconds Over Tokyo, etc. ), novelist (Johnny Got His Gun) and member of the Hollywood Ten. He is honored with a Dalton Trumbo Free Speech Fountain on the campus of his alma mater, the University of Colorado. His first novel, Eclipse (1934) was set in a fictional Colorado town based on Grand Junction, and many of the characters are identifiable as community leaders from his early years there.
